Application filed March 15,

f0 all whom may concern Be it known that l, FRANK hirer-r, a subject oi": the King of ltaly, residing at etroit, in the county of Wayne and State of llichigran, have invented certain new and useful improvements in lilusic-lieai Turners. of which the following is a specification, re ence being had therein to the accompanying drawings.

This invention relates to a music leat turning; device and has special reference to that type of device which may he i.- alled on music rack stand or other music leat support, whether the same be ot' an organ, pi .no or other instrument.

The primary ect of my invention is to provide a novel device by which leaves of a musical composition may be turned, one at a time, during the rendition 01 the composition, without the musician or others turning; the sheets or pages of the composition by hand, thus permitting oit entire attention being given to the music to be rendered and avoiding any momentary interruption.

Another object of invention is to provide a music leaf turning; device that will not injure the leaves or pages to be turned and which will notcause the sheet of music to become accidentally displaced due to y turning operation.

A further object of m invention is to provide a music leaf turning device embodyingspring actuated turning arms which are manually placed under tension. and are. adapted to be released by a novel pawl and pin shaft releasing, mechanism. The device also includes a restoring mechanism and anovel adjustable return member associated with the mechanism so that music may be repeated when necessary.

A still further object or my invention is to provide a device of the above type wherein the parts are constructed with a view of reducing the cost o'fmanu'tacture and at the same time retain those features by which durability, ease of assembling and installation are secured. With such ends in view, my invention resides in the novel construction to be hereinafter considered and then claimed and reference will now be had to the drawings, wherein Figure l is a front elevation oi the music leaf turning device, partly broken away;

Fig". 1a is a perspective view of a portion or the turning device, and

15 is a horizontal sectional view o't i portion of LllQ leat turning device.

In the drawings, 1 denotes an angle ledge havi a central upright 2 and said ledge and upright may torm part of a rack. support or holder for sheets of music, a hook, or leaves of a musical. composition, so that same will be held within the vision of amusician operating; on an organ, piano or other instrument. 1 is adapted The lge .L to support the lower edges of the leaves to be turned, in either direction during: the rendition ot the musical composition, and at the upright 2 is resilient retaining memher 8. adapted to engage in the central portion of a hook or sheets of music and retain the same on the ledge 1 witi the leaves or pages to be turned in either direction.

3 denotes a depending; shaft or arbor carby the ledge 1 contiguous to the up- 2, and the lower end of said shaft or -bor fixed in a horizontal support 4: formme" art of dependingbracket 5 carried by the led c l, at one side of the vertically dis- 6 denotes a plurality of superposed cup shaped spring holders non-rotatably mounted on the arbor 3 and between each one of these spring holders are the apertured heads 7 of turning arms 8, said arms being fiat and disposed in parallelism with the outer ends thereof provided with lea1 engaging; members 9. These members are placed in engagement with the outer tree edges of leaves of music and are adapted to turn the leaves when the inner edges thereof are bound in a suitable binding or are held by the retaining member 3; The leaf engaging members 9 extend upwardly in notches 10 provided therefor in the ledge 1 and are adapted for turning a music leat, without injury or dis placement of the same.

11 denotes coiled springs in the spring holder 6, said springs having convolutions thereof disposed about the hub portion 12 of said holders and each spring has one of its end convolutions thereof anchored, as at 13, in the holder and the other end convolution anchored, as at 141, in the head 6 of the arm 8 on said holder, said head closing; the holder and rotatable on the hub portion 12 thereof. The springs 11 are adapted to be placed under tension when the turning arms 8 are swung from the left to the right, considering Fig. 1, and when the arms are released from the right hand position there or", the tension of the springs 11 is sufiicient for swinging said arms from a right hand position to a left hand position.

15 denotes a side wall of the support 4r. and connecting said side wall and the bracket 5 is a transverse pin 16 supporting a plurality of spring pressed pawls 17, said pawls being pressed and held normally elevated by spring 18 on the support 4. The pawls are adapted to temporarily hold the turning arms 8 at the right hand side of the music lea't' turning device, with the springs 11 under tension, by engaging: depending; lugs 19 carried by the heads 7 of the turning" arms 8, said pawls corresponding in number to the arms and the lugs 19 thereof. It is therefore possible to swing turning arm from the left hand side of the device to the right hand side thereof and have it held in such position by a pawl, the lug 19 of the arm riding into engagement with the upper end 20 of the pawl to be temporarily held thereby.

21 denotes a rotatable pin shaft supported by the side wall and the bracket 5, said pin shaft having a plurality of beveled pins 22 positioned to successively engage the pawls 17, as best shown in Fig. 7. The pin shaft 21 is adapted to be intermittently moved to actuate two of the pawls 17 at one time, release the lugs 19 of the arms 8, and permit the springs 11 to turn said arms. The pins 22 are arranged in sets of two so that two of the pawls 17 will be actuated and this is necessary so that there will be clearance for the lug 19 ot' the arm to be released. As the arms swing in substantially a horizontal plane the lugs 19 move in an arc and would strike adjacent lugs it said lup's were not moved out ot the way. By observing- Fig. 153 and the dot and dash lines indicating the remarks in which the lugs swing. it will he noted that it is necessary to depress two of the pawls at a time, otherwise a. lug liberated by one pawl will impinge against an adjacent pawl, unless such adjacent pawl is lowered. lVhcn it is lowered, the hi, released by it will be temporarily held by the next adjacent pawl, but when the second pawl is restored to norma] position the second lug is moved back. This is true clear through to the last pawl, controllingthe last arm, wnich is the only arm that may be swrmgr back so that the last sheet of music may be repeated.

23 denotes a ratchet wheel mounted on the pin shatt 21 at the outer side of the wall 15 and normally engaging said ratchet wheel is a spring 2 1- to prevent a clockwise rotation thereof. (See Fig. 6). The ratchet wheel 23 is also engaged by a spring projected dog 2? reciprocable in a yoke 26 pivoted on the side wall 15, said dog extendingthrough a guide 27 ot' the wall 15, so that it cannot become laterally displaced. The free end 01 the yoke 26 is held normally elevated by a spring 28 carried by the wall 15, and pivotally connected to the free end of the yoke is a hanger 29 by which the free end of the yoke may be lowered and cause the dog thereof to impart movement in a counter-clock ise direction to the ratchet wheel 23, thereby rotating the pin shaft 21 and causing certain pawls 17 to be actuated. The elements to 29 inclusive constitute a ratchet mechanism for imparting n'iovement to the pin shaft 21, and this ratchet mechanism may be considered as part oi an arm releasing mechanism to be hereinafter considered.

3O denotes a guide at the upper end of the bracket 5 and slidable in said guide and on a portion thereof is a horizontally disposed rack 31, said rack having a portion thereof slotted, as at to receive the tork 33 of a.

bell crank 34 )ivoted as at 35 on the lower 7 7 end of the bracket 5. The rack 31 is held normally retracted by a coiled spring 36 and said rack is adapted to be shifted by the bell crank 34, said bell crank being connected to a cable, rod, or actuating member 37, which is adapted to extend to a point convenient to a musician, so that the musician may quickly use his hands or foot to o 'ierate the member 37.

38 denotes a pinion loose on the upper end of the arbor and the lower face of said. pinion has an adjustable return member 39 adapted to be positioned to engage upwardly arm 48 extending outwardly from. the

extending lugs 40, carried by the turning arms 8, adjacent the heads 7 thereof. This returning member can be shifted, so that it will return either or' the turning arms 8 from the left side of the device to the right side thereof, when it is desired to repeat part the music. It is now apparent that the actuznting member 37 may be pulled upon to swing the bell crank 34:, shift the rack 31 and swing the adjustable return member 39, so that a turning arm will be swung to the 1' lit, still considering Fig. 1, and thus permit of music being repeated. As the pins oi the 21 may not be in position for holdin returned arm, I have provided an a lock for temporarily retaining};

i119 arms during the rendition of the music.

41 denotes a guide on the outer side of the bracket and slidable in said guide is angular detent 42 adapted to bare its u 'zper end engage the rear end of the rack 31 and hold said rack in an extended position. The lower end of the detent 12 is connected by a transverse bar 43 to t e ha o'er and said transverse bar is connected by a coiled retractile spring 44 to the support 4 with the retractile force of said sprin holding the bar 43 normally elevated and the u ner end of the detent 42 against the lower of the rack 31, as shown in Fig. 3, so that the detent may immediately engage behind the rack when it is extended. A cable or suitable actuating member is connected. to the transverse bar 4:3 and this ac" member also extends to a point conven the musician, so that it may be pulled upon to release the arm retained at the right ha d side of the device, whether it be an arm t .t is to turn a sheet of music tor the amt time or a second time as would be case after repeating a portion of the musical score.

46 denotes an adjustable positioning and cushioning member slidaoly supported in opening of a radially disposed holder the arbor 3 and normally held in an em position by a coiled retractile spring 4;? connected to one end of said memhe and to an arbor The opposite end of the member has a cam or beveled portion 49 into engagement with which tie lugs ride when the arms 8 are swung from the right to the le' and with the lugs 40 engagir the cam s, lugs are supported slightly in advance of on another thus separating); t e members 9 o the arms 8 to a certain extent, and this separation is the result or" the arms being cushioned when assuming a leiit hand po tion. For instance, the sprin 's 11 i l fo cibly swing the arms from r15 when the lugs 40 engage the the adjustable arm positioning member l6, said member will be shifted against the action of the spring 47 and cushion the turning movement of the arms 8 just before reaching the 1 tion of the device the membeis 9 have been ment with the lower 05 es t the free edges or sioes 1e turning arms 8 swung o a 1'' 'li hand nosi."

L ion and the arms so ed v 'snective pawls 17. Now, actuating member is pulled the ratchet mechanism is actuated to movement to the in shaft releasing mechanism and the turning arm attached to the first sheet 01 music is released, permitting of said sheet being swung" "from the right to the left. After all the sheets have been turnen iroin right to left, only the last sheet can be turned baclr for repeating purposes, and this is accomplished by nulling on the actuating" member 37 when the arm restoriig mechanism will be actuated to swingtne last swine; arm bacl: to its original position, to temporarily held until the actuatir 4:5 is again pulled upon turned arm which is held by the After a turned arm ween 1'8-ili'lll19 l, a pull upon the member 15 to release the returned arm will not cause other arms to be released and two she turned one time, because of the man er in which the arms are h ld as shown in l. 14-, where it will be noted that the member 4L6 is spring retracted so that it may all times one of the lugs ll) and permit of only one arm being turned at a time.

E i ith oil? the lugs so closely assembled t is obvious that the return member 39 may, lug; l0 oi. lowermost the arms to right hand p eing necessary when there is 'on. t that the operation a. util- .y oi my device will be apparent without ther description and wh le in the drawthere illustrated preferred embodient of invention, it is to be understood hat the structural elements are susceptible 0 such changes in size, shape and manner or assemblage as fall Within the scope of the appended claims.
